I've been using Corona Alpha 4.1 for a while and decided to give Alpha 5.1 a go. After installing Corona Alpha 5.1 the Corona menu from the Plugins menu disappears and so do the render settings option to choose Corona. It looks as if Corona is not installed. I've tried it on Cinema 4D R17.048 Broadcast and Cinema 4D R16.050 Broadcast running on Windows 10 with the same results. If I go back and install Corona Alpha 4.1 everything goes back to normal. Do you have any advice on how to fix this?
